This was the response I got, just in case anyone else had the same question:

"The 340i utilizes a new engine, ECU, harness, and plugs so the engine management development essentially had to be started from scratch complete with new hardware. You are looking at a 6-9 month development cycle just for the tune assuming everything goes to plan (and it never does) and we are only about 2 months into it. Most of the major hard parts (intake, exhaust, etc) will be complete and selling before the tuning makes it to market."
